contained the product of 199 and such digit. As is customary in card indexes said cards B and C are contained within a. suitable case or box A having a cover a, being mounted upon a rod D, provided with a thumb head (Z, there being provided in the front of the box small grooves 66, through which, by means of a spring (not shown), suitable lugs (not shown) disposed upon the rod D are forced when the head d is properly turned, so that thus the rod D can be drawn through the cards from the box, or replaced in the same. File cards C are contained loosely within the box, they being provided with elongated vertical slots 0 by means of which they can be raised considerably above the body of the cards, as is shown in connection with two cards thus raised in Fig. 1.

The leader cards B and tab cards B are provided with similar slots Z) which allow, however, only a comparatively limited vertical movement, as is plainly shown in Fig; 3. Within the body of the box A is disposed a secondary or false bottom a provided with narrow transversely disposed slots (4 a row of said slots a being disposed adjacently to each side of said bottom a. Said slots a are adapted to receive tongues l) projecting downwardly from the leader cards B, as plainly shown in Fig. 3, so that said leader cards, by virtue of said connection with the false bottom a and by reason of their limited vertical movement, are in effect pivotally secured within said false bottom (1., and thus the bottom portions of said cards B have no movement longitudinally of the box, the whole body of cards being thus kept in proper position within the box which obviates all undue crowding of the cards in one portion of said body and the wide separation of the same at another portion, as shown in Fig. 1. i often find it desirable to provide the false bottom a" with transverse slots a arranged more closely one to the other, than shown in Fig. 5, in order that if the cards become unduly crowded in one portion of the case or unduly separated 1 may move a guide card from one slot of to an adjacent slot and thus remedy the congestion or undue separation of the cards. i have provided. on the first leader card 13 a suitable space 0 1, for any desirable advertisement, such as the name of the device, etc.

in Figs. 6 and 7 l have illustrated a modified construction for pivotally securing the leader cards within the case A and such construction involves a slight change in the and Said modified card is provided along its bottom edge with a stiffening memher 6* and longitudinally of the card adjacent to said lower edge are out two grooves 0, thereby providing tongue or bearing portions in the card itself. Said stiffening edge 6" may be formed by wrapping the lower edge of the metallic card l1) about a suitable iron or steel wire. I have disposed of the false bottom a and have provided in lieu thereof two longitudinal strips a one adjacent to each side of the box, said strips of being so disposed within the case A that their upper surfaces lie flush with the bottom of said case, as is plainly shown in Fig. 6, the stiffening member a and the bearing portions 6 being secured within the bottom of the box A and in the strips a respectively, by suitably grooving said box bottom and said strips. It will be noted that also this modified construction thus provides for a pivotal mounting of the card E within the box.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the means herein disclosed, provided the means stated by any one of the following claims or the equivalent of such stated means be employed.

l therefore particularly point out and distinctly claim as my invention 1. in a card index the combination of a suitable case; file cards and index cards contained in said case and arranged transversely of the same; and a rod extending longitudinally of said case, said file and in dex cards being provided with alined apertures for the reception of said rod, the apertures in said file cards being vertically extended relative to those in said index cards, whereby said file cards have limited vertical movement relatively to said index cards, substantially as described.

2. in a card index, the combination of a suitable case; file cards loosely contained in said case and arranged transversely of the same; index cards similarly arranged in said case but pivotally secured to the bottom thereof; and a rod extending longitudinally of said case, said. file and index cards being provided with alined apertures for the reception of said rod, the apertures in said file cards being vertically extended relatively to those in said index cards, whereby said file cards have limited vertical, as well as pivotal, movement, whereas said index cards have pivotal movement only.

3. In a card index, the combination of a suitable case; a false bottom in said case provided with a plurality of transversely disposed slots; file cards loosely contained in said case and arranged transversely of-the same; index cards provided on their lower edges with projections adapted to engage the slots in said false bottom; and a rod extendas said index cards have pivotal movement ing longitudinally of said case, said file and only. 10 index cards being provided with alined aper- Signed by me this 23rd day of Apr1l, 1907.
